I think most of the big ones have been covered here. Personally rooting for 1511. Every year they blow my mind with how much they do, and then manage to top it the next year. However, based on how finalist banners have been given out in previois years, its unlikely they make it for a couple more years since they just received finalist in 2022. As far as finalists go I think we could see 2338 become a serious contender this year or within the couple next, but are still a few years out on making HoF.
1816 was finalist back to back in 18 and 19 (then got hall of fame in 19)
1629 was also kind of a back to back finalist with 19 and 22
There have only been 4 years of championships where Impact/Chairman’s finalist has been given out so any historical data is kind of hard to reference.
359 and 2614 both are as good as the teams above them but are already in the Hall of Fame. It will be interesting to see if either get the finalist especially since 359 no longer auto qualify if the rules for Hall of Fame stay the same next year.
